I tried out Amplitube 2 and liked it, so I have version 3 on order (not out for a couple of weeks yet). When I tried the demo I pushed my computer to see what it would handle, and I got it to crack a little before I wanted it to. I think some of the reason is I'm running Windows 7 and both my interface and Cubase are using Vista drivers. The Cubase problem can get fixed on Monday but my interface doesn't have W7 drivers available yet. Anyway, I'm wondering how the Pod XT stands up to Amplitube as far as sound quality. If there's really no difference in that area I may just go that route to save CPU power. I know everyone has different tastes as far as sound goes. What I'm more concerned with is realism (as opposed to personal taste). I figure I can work with most tones as long as they sound believable. So I guess the main question is are Amplitube's models more believable than those on the Pod XT?
